Why? Because to a lay person I imagine a furiously whirling thing coming off a flying machine would look very like a propeller and would be fairly visible being comparatively large whereas a propeller might not.
It's now more than a rumour though I suppose it might still be inaccurate. From the lead article of The Press and Journal
newspaper the witness ...was walking her dog near the spot when she saw the gyrocopter's propeller fly off as it plunged out of the sky...
I'll leave you to make of that what you will.
